For L502X model: there are additional Fn+<Key> (sequences) that are not marked at all on the keyboard but underlying hardware sends them anyway. Here they are (if you find more add them to the table below):

You can use this command before and after to see how the battery consumption change (you need to disconnect sector first) :

grep rate /proc/acpi/battery/BAT1/state

To make this permanent, just add your working command in /etc/rc.local

Example :

modprobe acpi_call
/usr/share/acpi_call/m11xr2.sh off

Nvidia

Not tested yet.

I assume you need to :

Remove all previous Intel driver

Install Nvidia driver :

nvidia and nvidia-utils for the proprietary driver

OR nouveau for the open source driver

(In Sandy Bridge models at least) The Optimus setup consists of the integrated Intel chip connected to the laptop screen and the Nvidia card runs through this. As such, the Nvidia chip cannot be used without the intel chip (some other laptops have the option in BIOS to turn intel off and use just nvidia, but not this laptop). The only way to use the Nvidia is Bumblebee (or its fork, Ironhide). See Hybrid graphics#Nvidia Optimus

Screen

External Display

For Sandy Bridge models (L502x), there is ongoing work in the bumblebee project to enable HDMI output; however, as of 18 November 2011, this is not working. In these models, the HDMI port is connected to the Nvidia card (DGP), while the DisplayPort is connected to the Intel IGP. It is reported that as of now, one can use an external monitor connected to the DisplayPort.

Wlan

Some users will need to install the rfkill package in order to switch on the wireless adapter with the fn+F2 key.
Remember that wireless_tools will be needed for using a network manager such as networkmanager, see Wireless Setup for more information.

Note

It seems that rfkill used in conjunction with networkmanager will cause a normal shutdown to result in reboot when Wlan is powered off. To avoid this DO NOT install both together.

Bluetooth

Some users may need to run

hciconfig hci0 reset

to get blueman working

Power management

Special Touch Keys

The special touch keys are strangely mapped by default. One changes brightness, one does next track. They seem to be linked to the same key sequences as the Fn+F# keys that do the same job. To fix this, make this new file:
